IMPROVEMENT IN DIES FOR WELDING AND FORMING FROGS FOR PLOWS.

Specication forming part of Letters Patent N o. 183,093, dated Octoberl0, 1876; application filed September 12, 1876.

To all whom it may concern:

Be it known that I, CHARLES O. WILDER, of Monmouth, in the county ofWarren and State of Illinois, have invented certain new and usefulImprovements in Dies for Welding and Forming Frogs orAngle-Plates forBlows; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enablel others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanyin gdrawings, and to letters of reference marked thereon,which form a part of this specication.

The nature of my invention relates generally to improvements in dies formanufacturing that part of turning plows commonly known as the frog7 orangle-platefand especially to afrog in which a portion of the wing-sharebrace extends over the land-side.

bar, to form a brace for the land-side faceplate, all as hereinaftermore fully described.

In the accompanying drawings, Figure l is a perspective view of the bed-die with a frog in place therein. Fig. 2 is a perspective view of thebed-die alone. Fig. 3 is a top view of a frog of the class made by mydies. Fig. 4 is a side elevation of Fig. 3. Fig. 5 is a transversesectional view of the upper and lower die and frog between them, in theline x .fr of Fig. 2. Fig. 6 is a perspective view of the upper dieinverted. Fig. 7 is a perspective view of part of a plow, showing theuse of the class of frog herein described.

Referring to the parts by letters, letter A represents the bed-die orintaglio-die. In the upper side of this die is a recess, with aninclined side, B, in which a depression, b, is made, terminating in ashoulder, by', at its lower side, and a shoulder, b, at its forward end.The other side, C, of the recess extends diagonally back at its upperside, from the point of union with the side B, is curved, as shown inthe drawings, and terminates in a shoulder, c. The lower edge of theface C, from the face b to the shoulder c, is extended into the face B,to form a recess, E.

D is the upper or cameo die, and is formed to t the die A, with the frogF between them. F is the frog, consisting of the landside bar f, havingits forward pointed end j7 set over at a shoulder,f, to form a braceanda rest for the slip-share G. H is the wing-brace, having an upwardand rearwardly extended end, h, with a lateral extension, h', which,when the brace II is welded to the barf, extends over the bar f liushwith its farther side, and extends forward and terminates in a shoulder,h", immediately over the shoulderf.

In addition to the recesses hereinbefore described, the die A has anadditional rectangular recess, I, in its upper face at one side, and adat surface, i, extending forward therefrom; and the die D has a recess,I', immediately over the surface i, and a flat surface, i', over therecess I. The barf may be, in its blank form, laid on the die A at I,and struck into form bythe die D, as shown at Fig. l. The wing H is thenplaced thereon, and the two placed in the die A, and t-here thoroughlywelded and finished form given to the frog by blows from the die D. Theextension h rests and is given its nislied form in the recess E.

Fig. 7 illustrates the speca-l use in a plow of the extension h', (whenthe frog is seated and bolted in place in the usual manner,) to restagainst the upper part ot' the land-side face-plate, (shown by fullline, J,) and prevent its inward displacement in grinding andpolisliing.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The dies, constructed substantially as shown and described, forwelding together the land-side and the wing-brace, and striking thelatter into form, as set forth.

2. The dies, constructed substantially as shown and described, forstriking the landside into form preparatory to welding to thewing-brace, as set forth.

In testimony that I claim the foregoing as my own I aftix my signaturein presence of two witnesses.

CHARLES O. WILDER.
